After the sliding extrusion block is separated from the extrusion head, the second spring drives the first pull rod back to its original position, and the synchronous push plate returns to its original position through the pulling force of the first spring. When unloading again, the second cylinder drives the lifting rod to contract, and the first rack engages with the first gear again. After separation, the push block at the top pressurizes the sliding extrusion block, so that the sliding extrusion block moves downward to pressurize the extrusion head, so that the extrusion head is squeezed again. Therefore, continuous unloading can be achieved by lifting and lowering the lifting rod.

A top mold is fixedly connected to the bottom end of the first cylinder. The top mold is slidably connected to the bottom mold. The staff adds injection molding materials into the top forming groove. When the first cylinder is started, the first cylinder pushes the top mold downward to fit with the bottom mold, realizing the forming work.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. In the present invention, when the second cylinder is started, it drives the first support plate to rise. The first support plate drives the lifting rod to rise. The lifting rod drives the first rack to rotate with the first gear. The first gear drives the support cylinder to rotate. The support cylinder drives the lower mold to rotate. When the first rack is separated from the first gear, the lower mold just rotates 180 degrees. At this time, the formed keycap deflects into the interior of the workbench and is separated from the forming groove by the extrusion of the synchronous push plate. The staff can add materials to the other forming groove for re-forming work, thus realizing continuous work without separately collecting the keycaps, thereby improving work efficiency.

[0017] 2. In the present invention, after the first rack is separated from the first gear, the lifting rod continues to rise, and the lifting rod drives the pushing block at the bottom end to extrude the sliding extrusion block. The sliding extrusion block is gradually pushed up along the fixed frame under the pressure, and the sliding extrusion block extrudes the extrusion head. The extrusion head gradually moves away from the fixed frame, and drives the connecting rod to move. The connecting rod drives the first pull rod to move, and stretches the second spring. The movement of the first pull rod drives the push rod to move. The push rod slides along the second support rod and extrudes the connecting head. At this time, the two connecting heads are gradually deflected, so that the pressing block presses the synchronous push plate at the bottom end. The synchronous push plate at the bottom end drives the unloading block to extrude the key cap, so that the key cap is separated from the forming groove, facilitating unloading. After the sliding extrusion block is separated from the extrusion head, the second spring drives the first pull rod back to its original position, and the synchronous push plate returns to its original position under the pulling force of the first spring. When unloading again, the second cylinder drives the lifting rod to contract, and the first rack meshes with the first gear again. After separation, the pushing block at the top presses the sliding extrusion block, causing the sliding extrusion block to move downward to press the extrusion head, so that the extrusion head is extruded again. Therefore, continuous unloading can be achieved by the lifting of the lifting rod.

[0018] 3. In the present invention, after the forming is completed, pull the pull ring. The pull ring drives the second pull rod to move, the second pull rod drives the second support plate to move, and the second support plate drives the synchronous rods to separate from each other. The synchronous rods drive the second rack to rotate through the second gear, so that the two second support plates move away from each other, and the second support plate is separated from the bottom end of the lower mold. At this time, the lower mold can be flipped. After the flipping is completed, push the pull ring so that the second support plate supports the lower mold again to prevent the lower mold from being unstable during forming and unloading.

[0031] like Figure 1 - Figure 8As shown in the figure, the molding die assembly includes a lower die 41. The lower die 41 is arranged inside the workbench 1 at the top of the collection box 12.

A support cylinder 416 is fixedly connected to the middle of the side of the connecting turntable 415 away from the lower die 41. The middle of the support cylinder 416 is hollow. The support cylinder 416 is rotatably connected to the workbench 1. One support cylinder 416 penetrates through the workbench 1 and is rotatably connected to the workbench 1. A first gear 417 is fixedly connected to the end of the support cylinder 416 outside the workbench 1.

[0032] In this embodiment, when the second cylinder 31 is started to drive the first support plate 32 to rise, the first support plate 32 drives the lifting rod 33 to rise, the lifting rod 33 drives the first rack 34 to rotate with the first gear 417, the first gear 417 drives the support cylinder 416 to rotate, and the support cylinder 416 drives the lower die 41 to rotate. When the first rack 34 is separated from the first gear 417, the lower die 41 just rotates 180 degrees. At this time, the formed keycap deflects into the workbench 1 and is separated from the forming groove 411 by the extrusion of the synchronous push plate 413. The staff can add materials to the other forming groove 411 for re-forming work, so as to realize continuous work without separately collecting the keycaps, thereby improving work efficiency.

[0033] As Figure 1 - Figure 8As shown, the auxiliary unloading assembly includes a first support rod 42. The first support rod 42 is located inside the support cylinder 416 and the lower die 41. One end of the first support rod 42 is located outside the support cylinder 416. A support frame 421 is rotatably connected to the end of the first support rod 42 located outside the support cylinder 416. The support frame 421 is fixedly connected to one side of the workbench 1. A first pull rod 422 is slidably connected inside the first support rod 42. Both ends of the first pull rod 422 penetrate through the first support rod 42. A second spring 423 is arranged on the outer wall of the first pull rod 422 near the support frame 421. One end of the second spring 423 is fixedly connected to the support frame 421. A connecting rod 424 is fixedly connected to the end of the first pull rod 422 near the support frame 421. The connecting rod 424 is fixedly connected to the second spring 423. An extrusion head 425 is fixedly connected to the end of the connecting rod 424 away from the second spring 423. A fixed frame 426 is fixedly connected to one side of the support frame 421. A sliding extrusion block 427 is slidably connected to the middle of the fixed frame 426. The sliding extrusion block 427 is slidably connected to the extrusion head 425. A third spring 428 is fixedly connected inside the sliding extrusion block 427. A limiting plate 429 is fixedly connected to the end of the third spring 428 near the fixed frame 426. The limiting plate 429 is slidably connected to the fixed frame 426. A push rod 4210 is fixedly connected to the end of the first pull rod 422 away from the support cylinder 416. A second support rod 4211 is slidably connected to the end of the push rod 4210 away from the first support rod 42. The second support rod 4211 is located in the middle of another support cylinder 416 and is fixedly connected to the workbench 1. Connecting heads 4212 are fixedly connected in a circular array on the outer walls of the push rod 4210 and the first support rod 42 near each other. A deflecting rod 4213 is rotatably connected to the middle of the connecting head 4212. A pressing block 4214 is rotatably connected to the end of the deflecting rod 4213 away from the connecting head 4212. The bottom end of the pressing block 4214 is slidably connected to the synchronous push plate 413. The pushing assembly includes a second cylinder 31. The second cylinder 31 is located at the bottom end of one side of the workbench 1. A lifting rod 33 is arranged at the top end of the second cylinder 31. First support plates 32 are fixedly connected to both the top end and the bottom end of the lifting rod 33. The first support plate 32 at the bottom end is fixedly connected to the second cylinder 31. The first support plates 32 are both slidably connected to the limiting chute 11. A first rack 34 is fixedly connected to the middle of one side of the lifting rod 33. The first rack 34 meshes with the first gear 417. Push blocks 35 are fixedly connected to the sides of the top end and the bottom end of the lifting rod 33 different from the first rack 34. The push blocks 35 are slidably connected to the sliding extrusion block 427.

[0034] In this embodiment, the lifting rod 33 continues to rise, and the lifting rod 33 drives the push block 35 at the bottom to squeeze the sliding extrusion block 427. The sliding extrusion block 427 is gradually pushed up along the fixed frame 426 under pressure, and the sliding extrusion block 427 squeezes the extrusion head 425. The extrusion head 425 gradually moves away from the fixed frame 426, and drives the connecting rod 424 to move. The connecting rod 424 drives the first pull rod 422 to move, and stretches the second spring 423. The movement of the first pull rod 422 drives the push rod 4210 to move. The push rod 4210 slides along the second support rod 4211 and squeezes the connecting head 4212. At this time, the two connecting heads 4212 are gradually deflected, so that the pressing block 4214 presses the synchronous push plate 413 at the bottom. The synchronous push plate 413 at the bottom drives the unloading block 412 to squeeze the keycap, so that the keycap is separated from the forming groove 411, which is convenient for unloading. After the sliding extrusion block 427 is separated from the extrusion head 425, the sliding extrusion block 427 is located at the top of the extrusion head 425, and the third spring 428 continuously squeezes the limiting plate 429. The limiting plate 429 presses the outer wall of the fixed frame 426, so that the sliding extrusion block 427 can be positioned on the outer wall of the fixed frame 426. The second spring 423 drives the first pull rod 422 back to its original position, and the synchronous push plate 413 returns to its original position under the tension of the first spring 414. During this period, the staff can add materials to the forming groove 411 on the other side for re-forming work, so as to achieve continuous work without separately collecting the keycaps, thereby improving work efficiency. When the forming on the other side is completed, the second support plate 43 is separated from the lower mold 41, and the second cylinder 31 drives the lifting rod 33 to contract. The first rack 34 meshes with the first gear 417 again, so that the lower mold 41 is turned over 180 degrees again. The lifting rod 33 is squeezed and lowered, and the push block 35 at the top presses the sliding extrusion block 427, so that the sliding extrusion block 427 moves downward to press the extrusion head 425, so that the extrusion head 425 is squeezed again, and the pressing block 4214 presses the synchronous push plate 413 again. Therefore, continuous unloading can be realized by the lifting of the lifting rod 33, and the keycap is separated from the forming groove 411 and collected in the collection box 12.

[0035] As a preferred embodiment, the support assembly includes a second support plate 43. The second support plate 43 is slidably connected to both sides of the bottom end of the lower mold 41. Both sides of the second support plate 43 are slidably connected to the inner wall of the workbench 1. Synchronous rods 431 are fixedly connected to both sides of the bottom end of the second support plate 43. A second gear 433 is fixedly connected to the side of the synchronous rods 431 close to each other. A second rack 432 is engaged with the middle of the opposite side of the second gear 433. The second rack 432 is rotatably connected to the inner wall of the workbench 1. A second pull rod 434 is fixedly connected to the middle of one second support plate 43. The second pull rod 434 slidably penetrates through the workbench 1. A pull ring 435 is fixedly connected to the end of the second pull rod 434 located outside the workbench 1.

[0036] In this embodiment, after the forming is completed, the pull ring 435 is pulled. The pull ring 435 drives the second pull rod 434 to move. The second pull rod 434 drives the second support plate 43 to move. The second support plate 43 drives the synchronous rods 431 to separate from each other. The synchronous rods 431 drive the second rack 432 to rotate through the second gear 433, so that the two second support plates 43 move away from each other, and the second support plate 43 separates from the bottom end of the lower mold 41. At this time, the lower mold 41 can be flipped. After the flipping is completed, the pull ring 435 is pushed, so that the second support plate 43 supports the lower mold 41 again, avoiding instability during the forming and unloading of the lower mold 41.

[0037] As Figure 1 - Figure 8 shown, the die pressing assembly includes a bracket 21. The bracket 21 is fixed to the top end of the workbench 1. A first cylinder 22 is fixedly connected to the middle of the bracket 21. The bottom end of the first cylinder 22 is fixedly connected to an upper mold 23. The upper mold 23 is slidably connected to the lower mold 41.

[0038] In this embodiment, the staff adds the injection molding material into the top forming groove 411, and starts the first cylinder 22. The first cylinder 22 pushes the upper mold 23 downward to fit with the lower mold 41 to complete the forming work.

[0039] Working principle: First, the staff adds the injection molding material into the molding groove 411 at the top, starts the first cylinder 22, and the first cylinder 22 pushes the upper mold 23 downward to fit with the lower mold 41 to complete the molding work. After the molding is completed, the upper mold 23 is separated from the lower mold 41. Pull the pull ring 435, and the pull ring 435 drives the second pull rod 434 to move. The second pull rod 434 drives the second support plate 43 to move. The second support plate 43 drives the synchronizing rods 431 to separate from each other. The synchronizing rods 431 drive the second rack 432 to rotate through the second gear 433, causing the two second support plates 43 to move away from each other, and the second support plate 43 is separated from the bottom end of the lower mold 41. Then start the second cylinder 31 to drive the first support plate 32 to rise. The first support plate 32 drives the lifting rod 33 to rise. The lifting rod 33 drives the first rack 34 and the first gear 417 to rotate. The first gear 417 drives the support cylinder 416 to rotate. The support cylinder 416 drives the lower mold 41 to rotate. When the first rack 34 is separated from the first gear 417, the lower mold 41 just rotates 180 degrees. At this time, the molded keycap deflects into the interior of the workbench 1. At this time, push the pull ring 435 to make the second support plate 43 support the lower mold 41 again. Then the lifting rod 33 continues to rise, and the push block 35 at the bottom end of the lifting rod 33 squeezes the sliding extrusion block 427. The sliding extrusion block 427 is gradually pushed up along the fixed frame 426 under the pressure, and the sliding extrusion block 427 squeezes the extrusion head 425. The extrusion head 425 gradually moves away from the fixed frame 426 and drives the connecting rod 424 to move. The connecting rod 424 drives the first pull rod 422 to move and stretches the second spring 423. The first pull rod 422 moves to drive the push rod 4210 to move. The push rod 4210 slides along the second support rod 4211 and squeezes the connecting head 4212. At this time, the two connecting heads 4212 gradually deflect, so that the pressing block 4214 presses the bottom synchronous push plate 413. The bottom synchronous push plate 413 drives the unloading block 412 to squeeze the keycap, so that the keycap is separated from the molding groove 411, facilitating unloading. After the sliding extrusion block 427 is separated from the extrusion head 425, the sliding extrusion block 427 is at the top of the extrusion head 425, and the third spring 428 continuously squeezes the limiting plate 429. The limiting plate 429 squeezes the outer wall of the fixed frame 426, enabling the sliding extrusion block 427 to be positioned on the outer wall of the fixed frame 426. The second spring 423 drives the first pull rod 422 back to its original position, and the synchronous push plate 413 returns to its original position under the tension of the first spring 414. During this period, the staff can add materials to the molding groove 411 on the other side for re-molding work, thus realizing continuous work without separately collecting the keycaps, thereby improving work efficiency. When the molding on the other side is completed, the second support plate 43 is separated from the lower mold 41. The second cylinder 31 drives the lifting rod 33 to contract, and the first rack 34 meshes with the first gear 417 again, causing the lower mold 41 to flip 180 degrees again. The lifting rod 33 is squeezed downward, and the push block 35 at the top presses the sliding extrusion block 427.Lower the sliding extrusion block 427 to pressurize the extrusion head 425, so that the extrusion head 425 is extruded again, and the lower pressing block 4214 presses the synchronous push plate 413 again. Therefore, continuous discharging can be achieved by the lifting of the lifting rod 33, and the keycap is separated from the forming groove 411 and collected in the collection box 12.,
